delete, fixed

 

Last week my wideband was reading --- at idle, turns out i had a small exhaust leak. I fixed that and it reads fine now. Also Have you checked for boost/vacuum leaks, both may affect how the car runs.

 

was your wideband constant --- or did it bounce back and front

 

I have the exact same problem and I´m yet to find a solution.

 

Thats the same exact problem! I checked all my vacuum lines about 5-6 times, checked every line i could see with my plain sight but theres nothing wrong... after the car warms up the idle does get better but its the same scenario it still does it, the car drives perfectly fine its just the idle

And now in cold starts it takes about 2-3 attempts but thats nothing serious either

 

The problem happens when the ECU switches to closed loop.

If you ever find a solution, please, let me know. My car has this idle problem since I bought it used. Back then it had a Unichip piggyback, stock cams and some odd injectors and plugs. Even after a fully rebuilt engine and many new parts and still does the same. The only part I didn´t change is the front O2.
